Embodiment Construction

[0033]Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. First, an entire configuration of a vehicle 1 will be described with reference to FIG. 1. FIG. 1A is a side view of the vehicle 1 according to an embodiment of the present invention. Further, in the present embodiment, a form where the vehicle 1 has operator cabs 30 at opposite lengthwise sides thereof will be described as an example. Further, for convenience's sake, a lengthwise side and an opposite lengthwise side (the right and left sides of FIG. 1A) of the vehicle 1 will be defined as front and rear sides, respectively, in the following description. Thus, in FIG. 1A, a front side of the paper is defined as a right side of the vehicle 1 (vehicle body 20), and an inner side of the paper is defined as a left side of the vehicle 1 (vehicle body 20).

[0034]As illustrated in FIG. 1A, the vehicle 1 mainly includes a plurality of wheels 10, a vehicle body 20 supported an...

Abstract

There is provided a vehicle which can stably load or unload a long heavy load and lower a height of a working space necessary for loading or unloading the weight body. The loading/unloading apparatus suspends and maintains a load in a working beam installed between a pair of booms and rotates the pair of booms toward the left or right direction of a vehicle body, such that the load is unloaded from the vehicle body in a construction field or loaded from the construction field onto the vehicle body. Thus, the height of the working space necessary when the load is loaded or unloaded can be reduced as compared with a crane structure for loading and unloading the load by the fluctuation of a boom.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a vehicle, and more particularly, to a vehicle which can stably load or unload a long heavy load and lower a height of a working space necessary for loading or unloading the long heavy load.BACKGROUND ART[0002]For example, Japanese Patent Application Laid-Open Publication No. 1996-116619 (see FIGS. 1 and 2 and the like) discloses, as a vehicle for loading or unloading a load loaded on a vehicle body in a construction field, a vehicle including a self-propellant vehicle body, a loading / unloading platform installed on the vehicle body and on which a cover of a trough can be loaded, and a handling unit installed in the vehicle body to be extended or contracted, fluctuated, and pivoted.[0003]According to the vehicle, the cover is installed in the trough by holding the cover of the trough on the loading / unloading platform with an absorption unit installed at a tip end of the handling unit, extending or contracting, fluctuating,...
